Capillipedium GRAMINEAE Cymbopogon 



celled spikelets (especially the terminal ones) 1/3-2 times longer 



than the sessile ones 2 . C. glaucopsis 



1. Capillipedium parviflorum (R. Br.) Stapf (Andropogon micranthus Kunth) (L.SJ. 

 7: 244). Culms 40-120 cm. high; fls. and fr. VII-X. Old World tropics; locally 

 in An., Che., Ku. Thickets and grassy slopes. Fig. 452. 



2. Capillipedium glaucopsis (Steud.) Stapf (H.I.t. 3085). Culms suffruticose at base, 

 60-100 cm. high; fls. and fr. VII-X. India to eastern Asia and Malaysia; locally 

 in Che. Grassy slopes. 



86. Sorghum Pers. %%M (Kao Liang Shu) 

 Tall or moderately tall perennials or annuals with large open panicles of numerous 

 1-5-jointed racemes: spikelets binate, or ternate at the terminal joint of the rachis; 

 the sessile perfect, awned or awnless; the pedicelled staminate or neuter, awnless: 

 joints and pedicels slender, ciliate, never longitudinally grooved. About 35 species, in 

 tropical and subtropical zones; 3 in China. (Named for Sorgho, the Italian name of 

 the plant.) 



Key to the Species 



Perennial: panicle brs. simple; hairs of the infl. brown 1. S. nitidum 



Annual: panicle brs. compound or brg.; hairs of the infl. white 2. S. vulgare 



1. Sorghum nitidum (Vahl) Pers. (L.S.J. 6: 248). Culms 60-150 cm. high; fls. VIII; 



fr. IX. India to eastern Asia and Malaysia; locally in Ki., Ku. Grassy slopes. 



2. Sorghum vulgare Pers. ^ (Kao Liang; Tall Millet) (Hitch. 773). Culms 1-4 m. 

 high; fls. VIII; fr. IX. Cultivated in warm countries; locally in An., Ku. 

 Cultivated fields. Fig. 453. 



87. Schizachyrium Nees S#^M (Lieh Fu Ts'ao Shu) 



Low annuals (ours) with slender culms and spatheate infl. of solitary racemes: 

 spikelets binate; the sessile perfect, awned; the pedicelled reduced to awned glumes: 

 joints and pedicels usually thickened upwards with scarious cupular or toothed appen- 

 dages at the apex. About 50 species, pantropic; 3 in China. (Greek: schizo, to split, 

 and achyron, chaff, alluding to the bipartite fertile lemma.) 



1. Schizachyrium brevifolium (Sw.) Nees (Andropogon brevifolius Sw.) fl^M (Lieh 

 Fu Ts'ao; Broken-lemma Grass) (L.S.J. 7: 243). Culms 20-60 cm. high; fls. IX; 

 fr. X. Tropical and subtropical regions; locally in An., Che., Ku. Moist shady 

 places or rocky slopes. Fig. 454. 



88. Cymbopogon Spreng. Oilgrass H^M (Hsiang Mao Shu; 



Fragrant-grass Genus 



Mostly aromatic perennials with spatheaceous infl. of binate racemes: each pair of 

 racemes subtended by an inflated boat-shaped spathe: spikelets binate; the lowest 

 pair in one of the binate racemes homogamous (both awnless, staminate, or neuter.) 

 About 30 species, in tropical and temperate zones of the Old World; 5 in China. 

 (Greek: kumbe, boat, and pogon, beard, alluding to the boat-shaped spathes.) 



1. Cymbopogon tortilis (Presl) Hitch. (L.SJ. 7: 246). Culms 50-120 cm. high; fls.
